Electrical performance
| Item 项目 | Test method 测试方法 | Criteria 判定标准 |
| Standard charge 标准充电 | Charge at CC mode at 260mA until the pack voltage reaches 21.3V, change to CV charge mode, when the charging current is no higher than 65mA, stop charging. 以260mA恒流充电，当电压达到21.3V后，转为恒压充电，充电电流小于或等于65mA时，充电结束。 | |
| Rapid charge 快速充电 | Charge at CC mode at 1300mA until the pack voltage reaches 21.3V, change to CV charge mode, when the charging current is no higher than 65mA, stop charging. 以1300mA恒流充电，当电压达到21.3V后，转为恒压充电，充电电流小于或等于65mA时，充电结束。 | |
| Capacity 容量 | Rest the battery for 1 hour after being fully charged by standard charging mode. Keep discharging the battery at current of 260mA until the cut-off is triggered. 标准充电后搁置1小时，以260mA电流连续放电至电池组放电保护。 | Discharging time≥5hrs 放电时间≥5小时 |
| Capacity measured at 10C discharge 10C放电容量 | Rest the battery for 1 hour after being fully charged by standard charging mode. Keep discharging the battery at current of 13A until the cut-off is triggered. 快速充电后搁置1小时，以13A放电至电池组放电保护， | Discharging time≥5.4mins 放电时间≥5.4min |
| Cycle life 循环寿命 | Leave the battery for 10 mins after rapid charged. Keep discharging the battery at current of 13A until the PCB protection is triggered. Rest the battery for 45 mins before the next charging/discharging cycle, until the battery discharging capacity are below 80% of the nominal capacity in continuous twice. The test is over. 快速电后搁置10min，以13A电流恒流放电至电池组受保护板过放保护无输出，搁置45min，再进行下一个充放电循环，直至连续两次放电容量低于额定容量的80%，试验结束。 | Cycle life is no less than 200 times 循环次数不低于200次 |
